I think i've been spoiled by recent games like Bad Company 2, Alpha Protocol, ME2 and MW2 with their blinking lights and indicators for every little thing. It's truly refreshing to play a game that (for a lack of a better phrase) hates me.
I have no idea if I'm sneaking past this guard undetected, and I LOVE IT.
I love that there are bunch of ways into this stronghold, and that you only tell me about a couple possible approaches. It reminds me of playing Hitman over and over just to see if taking a left down that corridor would work better than stabbing all those bystanders.
I also appreciate having the option to get bored of crouching and just sprint right up to everyone and shoot them in the face.
I can't believe I've let this sit on my shelf for half a decade.
